Definitions

  • This invention relates to a scaffold structure made up of a plurality of beams, as opposed to the usual tubular scaffold structure, wherein the structure has sufficient strength to resist or carry loads greatly in excess of those which could be met by an equivalent tubular scaffold structure.
  • the beams comprise what are referred to in the art as soldiers each of which may be in the form of a single elongate steel member of square or rectangular cross-sectional form or in the form of a pair of spaced parallel elongate steel members secured together by connector plates at their ends and also secured together intermediate of their ends.
  • soldiers each of which may be in the form of a single elongate steel member of square or rectangular cross-sectional form or in the form of a pair of spaced parallel elongate steel members secured together by connector plates at their ends and also secured together intermediate of their ends.
  • One such known form of soldier comprises a pair of spaced channel section elongate steel members secured together in parallel back-to-back relation with rectangular end connector plates welded to the ends of the channel members.
  • a series of longitudinally spaced aligned apertures is provided along the length of the channel members for reducing the overall weight of the soldier and also for providing attachment locations for other scaffold elements.
  • a connector at an end of, for example, a vertically disposed soldier to which can be bolted the respective end connector plates of horizontally disposed soldiers and a further vertically disposed soldier.
  • Such a connector has been proposed generally in the form of a cube having six planar surfaces comprising mounting plates to which can be bolted the end connector plates of up to six vertically and horizontally disposed soldiers i.e. two vertically disposed soldiers one above and one below the connector and up to four horizontally disposed soldiers. It will be appreciated that, if such a connector is utilised to connect six soldiers together as described above, it will be a time consuming exercise to achieve all of the bolted connections between the soldier end connecting plates and the respective mounting plates of the connector.
  • a connector for connecting two or more beams together comprising at least two surfaces each of which is engageable by a respective end plate of a said beam; a pair of limbs projecting outwardly of at least one said surface for receiving a beam therebetween, each said limb having an aperture therein and an end abutment spaced from the said surface, the abutment on one limb being spaced further away from the said surface than the abutment on the other said limb, a wedge clamping member insertable through the apertures in said limbs and through the beam to engage that side of the end plate thereof remote from the connector and to engage the said abutments to effect pressure engagement of the end plate against the said surface of the connector.
  • Said at least two surfaces of the connector may be perpendicular to one another whereby two beams may be connected to one another in mutually perpendicular relation or said at least two surfaces of the connector may be co-extensive and parallel to one another whereby two beams may be connected to one another in co-axially aligned relation.
  • the connector includes at least one surface adapted for bolting connection to an end plate of a beam.
  • the connector conveniently comprises at least one surface adapted for bolting connection to an end plate of a beam and a plurality of further surfaces extending co-extensively and perpendicular to said at least one surface, each of said further surfaces including a pair of limbs projecting outwardly thereof for receiving a beam therebetween, each said limb having an aperture therein and an end abutment spaced from said further surface, the abutment on one limb being spaced further away from said further surface than the abutment on the other said limb, a wedge clamping member insertable through the apertures in said limbs and through the beam to engage that side of the end plate thereof remote from the connector and to engage said abutments to effect pressure engagement of the end plate against the said further surface of the connector.
  • the connector may comprise a pair of spaced apart parallel surfaces each of which is adapted for bolting connection to an end plate of a beam and wherein said further surfaces as described in the preceding paragraph extend between said pair of parallel surfaces.
  • the connector conveniently comprises four said further surfaces arranged in two opposed pairs, each of which pair is perpendicular to the other pair.
  • the connector is configured to permit the joining together of up to six soldiers whereby a plurality of such connectors may be utilised to construct a three-dimensional scaffolding made up of a plurality of vertically and horizontally disposed soldiers.
  • the connector comprises a pair of spaced apart parallel generally square mounting plates 10 and 12 each of which is provided with four apertures 14.
  • the plates 10 and 12 will be disposed in a horizontal plane and are conveniently referred to hereafter as the upper mounting plate 10 and the lower mounting plate 12.
  • Said plates are spaced apart by four symmetrically disposed square cross-section tubular spacer elements 16 welded at their top and bottom ends respectively to the undersurface of the upper plate 10 and the upper surface of the lower plate 12.
  • Such spacers 16 are of equal length, whereby the upper and lower mounting plates 10 and 12 are secured parallel to one another, and are located such that the radially outermost surface 18 of each spacer 16 is parallel to a respective edge of the upper and lower plates.
  • Each spacer 16 is provided with a pair of limbs 20-22 and 24-26 respectively projecting outwardly thereof at both its upper and lower ends immediately adjacent respectively the under surface of the upper mounting plate 10 and the upper surface of the lower mounting plate 12.
  • each said pair of limbs 20-22 and 24-26 is constituted by the outer ends of two right-angled members welded between adjacent spacers 16 and also welded to the respective lower surface of the upper mounting plate 10 and the upper surface of the lower mounting plate 12.
  • four such right-angle members are provided at each of the upper and lower ends of the spacers 16 to provide two said pairs of limbs each of which comprises a pair of parallel planar elements spaced apart by the width of the spacer 16.
  • each upper pair of limbs 20-22 extends further radially outwardly of the outermost surface 18 of its associated spacer 16 than the associated lower pair of limbs 24-26.
  • Each pair of limbs is provided adjacent their outer ends with an abutment 28 in the form of a cylindrical member welded between the limbs through aligned circular apertures therein such that the abutments 28 between upper pairs of limbs 20-22 are spaced further away from the respective surfaces 18 than the corresponding abutments between lower pairs of limbs 24-26.
  • the connector also includes a wedge clamping member 30 associated with each spacer 16 and being insertable through the apertures defined between the abutment 28 on each pair of limbs 20-22, 24-26 and the adjacent outer surface 18 of the associated spacer 16.
  • a horizontally disposed soldier 32 may be located between the pairs of limbs so that the end plate 34 of the soldier engages the outer surface 18 of the associated spacer 16 and is secured to the connector by the wedge 30 which effects pressure engagement of the soldier end plate 34 against the said outer surface 18 of the spacer.
  • a vertically disposed soldier 36 may be secured to the upper mounting plate 10 as illustrated in Figure 2 by means of suitable bolts (not shown) passing through aligned apertures in the end plate 38 of the soldier 36 and the apertures 14 in the mounting plate 10.
  • the connector illustrated herein is capable of joining together up to six soldiers i.e. two vertically disposed soldiers each of which is secured by bolting to a respective upper and lower mounting plate 10-12 of the connector, and up to four horizontally disposed soldiers each of which is secured to the connector by the wedge clamping member 30 effecting pressure engagement of the respective soldier end plate against the respective outer surface 18 of a spacer 16.
  • connectors of the type described and illustrated herein may be utilised to build up a three-dimensional scaffold structure wherein each connector acts as a node between up to six soldiers.
  • a connector for connecting two or more soldiers together wherein the connector comprises at least two surfaces each of which is engageable by a respective end plate of a said soldier and wherein at least one of said surfaces includes a pair of limbs and a wedge clamping member of the general type hereinbefore described.
  • a connector in accordance with the invention may comprise only two surfaces for connecting two soldiers together, the two surfaces being perpendicular to one another, and one or both of said surfaces including a said pair of limbs and being provided with a wedge clamping member for securing a said soldier to a said surface.
  • one of said surfaces may comprise a mounting plate for bolting connection to a soldier end plate and the other surface may include the said limbs and wedge clamping member.
  • securing means i.e. by bolting or by wedge clamping may be provided on a plurality of surfaces of a connector constructed in accordance with the invention.
